The well-known Chinese manufacturers of industrial sewing machines, Zoje Sewing Machine, has invested $20 m to equip its production line for producing first quality products and further improve its machining capacity. The production line has been researched, developed and produced by Japan Makino Milling Machine. It is claimed to be the first in the sewing industry to adopt large scale automatic and SMC product line.
Zoje’s newly developed product line consists of 3 lines, eighteen machine centres and 3 conveying dollies. Every product line is controlled by a computerised central control system, which also simultaneously controls the cutting tools, fixtures and dollies, etc. The device has been integrated with ‘professional 5’ system and multifunctional software. Each set of device is provided with an independent dust and fog collection system. It is also provided with an enclosed ring formed by a 3 coordinate grating ruler, which can effectively remove any manufacturing error of lead screw, so as to guarantee the repetitive precision of the device at any coordinates.
Each device has also been provided with 120 large-scale cutting tools having the function of mixed random machining for multiple varieties. The central control system can also carry out digital transportation by connecting the cutting tools with Internet. The device can also perform such powerful functions as recording the data & service life of cutting tools, providing damage report of these tools, maintaining production record and raising malfunction alarm.
One of the unique feature of this line is that these 2-dimensional fixtures can carry out unattended functioning for 4-hours at night, leaving the normal production unaffected, even during conditions of malfunctioning or stoppage of some machines or maintenance fixtures.
The designed capacity of this project is 80,000 sets/year, operated 24 hr/day, and the loading rate of the entire device is above 90%, which can undertake batch production tasks of three major series, totalling 13 types of working pieces for the company.
